DESCRIPTION:Ptychography is a computational imaging method that\, like hol
 ography\, solves the phase problem. However\, it has distinct advantages o
 ver holography and other phase retrieval methods. The apparatus does not n
 eed accurate calibration\, the data is significantly immune to partial coh
 erence effects\, and three-dimensional effects can be removed from the ima
 ge data. It works over all wavelengths (Terahertz\, IR\, visible light\, E
 UV\, soft and hard X-rays\, and for high-energy electrons)\, and is theref
 ore making significant inroads into the characterisation of materials at m
 any length scales.
